IMPROVEMENT IN FASTENING- FOR CUTTER-HEADS, PULLEYS, 8m.

-HOM*- The Schedule referred to in these Letters Patent and making part of the same.

To (ell whom yit nul-y concern:

Be itknown that we, JOHN DU Bols and EDWIN F. BEUGLER, of the city of Williamsport, in the county of Lycoming and State of Pennsylvania, have invented a new and useful Improvement for Fastening Iulleys, Cutter-Heads, 85e., on round shafts without the use of key-seat or set-screws; and we hereby declare that l the following is a full and exact description of the against the end of the hub, thereby drawing the bush-- ing into the huh, and contracting the bushing onto the sha-ft, and keying it tirmly in the position desired.

When the nut is used in. the end of the bushing, a screw-bolt is fitted in the nut of the bushing in such a manner as to draw the bushing in the hub, as above described, reference. being had to the accompanying drawings forming part of this specification, iu which- Figure l is a perspective vieu' of apulley and eutter-head upon a shaft.

Figure 2 is a sectional view of pulley, cutter-head, and shaft, divided in the centers.

Similar letters of reference in the two figures indieate corresponding parts..

A represents the shaft to be fastened upon.

B is the bushing inserted in hub of pulley or outter-head' (.l.

D is nut on bushing of pulley C.

E is a screw-limit in end of bushing used in the cutter-head.

,F is the head of screw-bolt E for turning the saine.

G is a collar on the screw-bolt E for the purpose of holding it in position while forcing the bushing out of the cutter-head, thereby loosening the cutter-head from the shaft.

H is an adjusting screw-bolt to regulate the position of the cutter-head on the shaft.

l I is a jam-nut on the adjusting screw-bolt H..

What we claim, and desire to secure by Letters Patent, is-

Ihe taper bushing, substantially as setforth, for the purposes within named.

Witness our hands in the matter of our application for Letters Patent on our improvement in fastening pulleys, entrer-heads, 8vo., on round shafts.
